CAR=COUPLING.

SFECIFICATION forming part of Letters Patent No. 312,114, dated February10,1885.

Application filed June 13, 1884. (No model.)

To aZZ whom it may concern:

Be it known that 1, WILLIAM Jnsrnn HAD- DEN, a citizen of the UnitedStates, residing at Danville, in the county of Vermillion and State ofIllinois, have invented certain new and useful Improvements inOar-Couplings, of

I which the following is a description.

This invention relates to that class of devices which are designed tocouple cars automatically; and its object is to hold the pin set readyto drop, to guide the link into the drawhead, to drop the pin throughthe link when two draw-heads bump together, and to raise the pin whendesired, all to be done mechanically.

To this end my invention consists in the construction and combination ofparts forming a car-coupling, hereinafter described and claimed,reference being had to the accompanying drawings, in which- Figure 1 isaside elevation of two drawheads, showing a coupling according to myinvention, and aportion of two cars. Fig. 2 is a longitudinal verticalsection of one drawhead and adjacent parts, and Fig. 3 is an endelevation of the same.

A represents a portion of a car to which a drawhead, B, is attached, asusual. This draw-head is bell-mouthed, as usual, to receive the link;but I provide a scoop-shaped guide, 0, to raise the end of the incominglink, in case it is considerably lower than the mouth of this draw-head,by allowing the end of the link to slide up the guide. The guide 0 ispivoted in the draw-head at c to hang down to an angle of aboutforty-live degrees when ready for usethatis, when itis held up by thesupporter D. This supporter D consists of a sleeve fitted about thedraw-head to slide longitudinally thereon, and it is pressed forwardcontinually by a spring, E, to project beyond the draw-head.

F is theshacklepin, which may be ofthe usual form, having an eye, f, toreceive the hook of a chain, G, which is wound upon an eccentric orcam-shaped roller, H, mounted on a shaft, I, which is journaled upon thebody of the car, and provided with a crank, J, at each end. Thesupporter or sleeve D is provided with a perforated boss, d, to receivethe pin F, the boss being high enough to hold the pin in a standingposition. Through the hole 1 in the boss fits the pin loosely. Thepin-hole b through the upper portion of the draw-head is elongatedlongitudinally to the head to give the pin more freedom to drop into it.When the sleeve P is in its forward or normal position, its pin-hole isforward of the pin-hole b, so that a pin in the sleeve will stand uponthe draw-head in front of the hole. WVhen two draw-heads are to beengaged, a link,K,should be arranged in the opposite draw-head, toenterthe draw-head with the pin set as described. Then the two sleevesmeeting will crowd each other back, moving the pin to enter and dropinto the holeb through the link. WVhen the sleeves thus recede, theguides will swing down alittle within the draw-head, so as to beprotected from the force of a concussion. The bearings for the shaft Iare brackets L, each shaped to receive one of the cranks J when theshaft is slid endwise in its bearings, so that the pin may be raised andthe crank slid onto the bracket to hold the pin raised when it is notdesired to couple two cars when they come together.

By the use of this coupling the cars will couple automatically when theycome together, and they may be set ready to do so from either side ofthe car without danger to the operator.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination, with a car draw-head, of the scoop-shaped guide 0,hung within the mouth of the drawehead, and pivoted therein at c, thesleeve D, fitted around the draw-head and around the guide 0, to raisethe latter by forward movement, and the spring E, actuating the sleeveto such forward movement, substantially as described.

2. The combination, with a car draw-head, of the shackle-pin raiserconsisting ofthe roller H, the shaft I, carrying the same, adapted toslide endwise, and provided with cranks J, the brackets I", supportingshaft 1, and adapted to support the cranks J, to prevent the shaft fromturning when slid endwise, as described, and the connecting-chains G,substantially as described.
